SPECIFICATION forming part of Letters Patent No. 324,900, dated August 25, 1885.

Application filed September 30, 1884.

To all whom it may concern;

Beit known that I, Lnvt D. VAN VALK- ENBURGH, of Holyoke, inthe county of Hampden, State of Massachusetts, have invented a certain new and usef'ul improvement in Spindles and Bearings, of which the following is a description sufficiently full, clear, and exact to enable any person skilled in the art or science to which said invention appertains to makeand use the same, reference being had to the accompanying drawings, forming apart of this specification, in which- Figure l is a side elevation of myimproved spindle,including the bearings therefor; Fig. 2, a vertical longitudinal section of the same; and Fig. 3 a side elevation ofthe bushing and its pat-kin g detached, the packing being shown in section.

Like letters ot reference indicate correspending parts in the different figures of the drawings.

My invention relates more especially to that class of spindles which are employed on single rail-Spinnin g frames, twisters, 85e.; and it consists in a novel construction and arrangement ot' the parts, as hereinafter more fully set forth and claimed, by which a more desirable and cii'ective article of this character is produced than is now in ordinary use.

The nature and operation of the improvement will be readily understood by all conversant with such matters from the following` explanation.

In the drawings, A represents the body or stand, B the spindle proper, and C the step. The spindle is provided with a sleeve-whirl, l), which is chambered, as shown at a, to pass over the upper portion of the body A, the sleeve-whirl l) being provided at its lower end with a pulley or whirl, E, for the drivingbelt. The sleeve-whirl is firmly attached to the spipdle and is beveled orinelined as shown at m to center77 the bobbin and prevent it from vibrating. An elongated tubular bushing, (i, provided Vwith a threaded boss, at either end, is screwed into the upper end of.' the body A, which is interiorly threaded to receive it, and disposed around the bushing between it and the interior walls ofsaid body 5o there is a packing, consisting preferably of a piece ol' ordinary tubular wicking, ll, extend- (Nn model) ing from near the lower to the upper boss, or so as to nearly cover the central portion of the bushing. The' body A is enlarged near its center or provided with a thick annular ange, J, which rest-s on the rail ot' the frame when the spindle is in position for use. It is also exteriorly threaded and provided with the nut R for securing it in position on the rail. The ange J basa chamber or reservoir on its upper side, as shown at z, for receiving and holding the oil, the chamber being provided with a cover, fi, having a suitable induction-orifice, q, through which the oil may be poured. There is a duct or conduit, a, eX- tending from the bottom of the chamberz through the upper portion ot' the body A, to permit the oil to pass from the chamber to the wicking H, and also two ducts or con,- duits, a a, extending through the upper portion of the body of the bushing G, to permit the oil to pass from the wicking to the spindle B. An interiorly-threaded holder or thimble, K, is screwed onto the lower end of the body A, which may be secured in any desired position by the check nut L. The step (l, which is adapted to receive the lower end of the spindle B, is secured in a vertical position within said holder and is provided with a lateral duet or conduit, l, through which oil may pass to the spindle from the reservoir r, the reservoir being filled through the duct a. A bent guard, M, is inserted in the flange J, and extends over the lowerportion of whirl E, to prevent the spindle from being accidentally thrown or withdrawn from its step. This guard may be readily turned to one side when it is necessary to remove the spindle. A slot, h,is cut in the upper end of the bushing G for receiving a screw-driver or other suitable implement for turning the bushing as it is `screwed into or withdrawn from the upper portion of the body. I form a groove or airpassage, d, inthe upper boss,f, for admitting air to the chamber or space around the bushing` in which the wicking is disposed, and thereby facilitating the absorption of oil; but this may be omitted, if desired.

l do not confine myself to the use of wicking for covering the bushing, as any suitable absorbent or conductor of oil may be elnployed which is adapted to perform the same IOO functions; neither do I confine myself to using but one duet, r, leading from the chamber z, or two ducts, a, in the bushing Gr, as these numbers may be varied as found necessary or desired; nor to using the spindle with single rail-spinning frames. In spindles of this character much difficulty is experienced in properly lubricating the upper bearings or that portieri which is near the top of the body A. Difficulty is also experienced in adjusting the spindle vertically in such a manner as to cause the bobbin to be iilled or built properly. My invention is designed to overcome these and other objections and difficulties, and to that end I make use of the moans described,

whereby the spindle is perfectly lubricated and may be readily adjusted at any required height. The reservoir r is auxiliary to that in the tlange z, and will not ordinarily be. required, as sufficient oil usually finds its Way through the ducts o a and down the body of the spindle to lubricate the step C, without the necessity of iilling the lower reservoir; but in case it does not, the step may be oiled through the hole fn. The check-nut Land hole n may be dispensed with, if desired, as the holder K, when screwed tightly onto the lower end of the body, will remain in position, and the reservoir o' may be filled before the holder is attached.

It will be obvious that the wicking and bushing afford a very simple and effect-ive means of lubricating` the upper bearing of the spindle; also that the adjustable holder will enable the spindle to be adjusted vertically in any desired position.

Having thus explained iny invention, whatl step C, having the duct I, the body A, provided with the nut L, and the spindle B, substantially as described.

2. The combination ofthe body A, provided with reservoir e and with duct e, nuts L R, spindle B, provided with whirl E, the bushing G, provided. with bosses f, with the duct a, and with the groove d, the wicking H, the step C, provided with the duct l,.and the holder K, provided with the reservoir r and hole n, substantially as described.

3. The combination of the following instru mentalities-to wit, a spindle, a body in which the spindle is supported 5 an adjustable holder carrying a step for the spindle and disposed at the lower end of said body, a reservoir for oil disposed near the center of said body, a bushing for the spindle disposed in the upper portion of said body, a wick or absorbent for conveying oil from said reservoir to the upper portion of said bushing, a duct for the oil leading from said reservoir to the wicking, a `duct for the oil leading from the wicking through the bushing to the spindle, a whirl or pulley for the spindle, and a nut or means for securing the body to the rail of a spinning-trame, substantially as described.
